Rapid prototyping automates the fabrication of a prototype part from a three-dimensional (3-D) CAD drawing. These physical models convey more complete information about the product earlier in the development cycle.

Load cells are force sensors that often incorporate mechanical packaging to fit into testing and monitoring systems. They can be used for tension, compression, and/or shear measurement, and can be configured to measure force or load along one or more axes.

Mortar and pestle sets are used to crush, grind, and mix small solids or slurries. The mortar has the shape of a small, heavy walled cup. The pestle looks like a miniature baseball bat, the end of which is used for crushing or grinding.
